Kyle Busch was not happy with Toyota Sunday after running low on fuel at Dover International Speedway.

Now, Toyota officials are not happy with Busch for his profanity-laced tirade after the race, which was aimed at Toyota Racing Development.

Busch dominated the race at Dover, leading 302 of 400 laps. But his car did not get the fuel mileage that other drivers did, forcing he and Joe Gibbs Racing teammate Denny Hamlin to pit late in the race. Busch wound up finishing seventh and Hamlin was eighth, both a lap down.

Afterward, Busch lashed out at TRD, which supplies engines to Gibbs and other Toyota teams.

“Thank you TRD,” Busch said on his team radio after the race. “(Expletive) us out of another one. Piece of (expletive) (expletive).”

According to thatsracin.com, Toyota officials are not happy with Busch over his comments. TRD president Lee White confirmed to Sporting News on Thursday that Toyota officials have talked to team owner Joe Gibbs about the incident.

"We're as frustrated as he was that he didn't win that race considering how many laps he led, considering he and Denny both literally dominated the race,” White told ThatsRacin.com. “We're as disappointed as he was. However, we've got used to saying, 'That's just Kyle, you know.' But this is a bit of a special case.

"We're extremely disappointed in his negative comments and the tone of the comments after the event. It is under discussion as we move forward. We certainly are very disappointed.”

Hamlin also was frustrated after the race, but did not blame Toyota or TRD for his problems. Dodge’s Brad Keselowski won the race by stretching his fuel mileage and running the final 89 laps on one tank of fuel. Chevy’s Jimmie Johnson also did not have to stop after pitting around the same time Keselowski did.

Busch and Hamlin, however, were not able to conserve enough fuel to make it to the end.

“I can’t control all this fuel-mileage s---,” Hamlin said. “It’s just this fuel-mileage game sucks.”

White said Toyota engines did not have a problem with using too much fuel.

"Every one of our teams ran full power, full rich (fuel mixture) and kicked their ass,” White told thatsracin.com. “All six of them and some other teams did, too. It wasn't just TRD power that had this issue. The race didn't fall their way and we've seen it happen more lately.

"I'm not going to apologize for TRD. … We should have won the race but circumstances didn't work out that way and I'm sorry. We don't have anything to apologize for.”

Busch often lashes out and vents his frustration after disappointing finishes, but rarely has he targeted his rant at Toyota.

White told Sporting News on Thursday that Toyota officials have talked to team owner Joe Gibbs about Busch's comments.

"At this point, we are leaving it up to coach. They’re working on a resolution and I’m sure it will be just fine," White told Sporting News.

Sunday was not the first time this year that Busch has been frustrated with Toyota engines. He fell out of three straight races in June because of engine problems.

"We shared his frustration (earlier this year) without question and have worked diligently to get better and are still working and will never stop working," White told Sporting News. "We all know Kyle is extremely passionate. We love that passion. We embrace that passion.

"Kyle is a brilliant driver. He and Samantha are a part of our family. Occasionally families have squabbles. We’ll find our way through it and there is nobody better than the Coach to make that happen."
